North Korea 'to restart Yongbyon nuclear reactor'


Williamson: "Most people believe North Korea does not want all-out war"

North Korea says it will restart all facilities at its main Yongbyon nuclear complex, including a reactor mothballed in 2007.

In a statement, it said the move would bolster North Korea's nuclear forces "in quality and quantity".

The move is the latest in a series of measures by Pyongyang in the wake of its third nuclear test in February.

It has been angered by the resultant UN sanctions and joint US-South Korea annual military drills.

In recent weeks the communist state has issued a series of threats against both South Korean and US targets, to which the US has responded with high-profile movements of advanced aircraft and warships around the Korean peninsula.


North Korea's announcement effectively undoes international efforts to constrain its nuclear programme. But restarting the reactor at Yongbyon will take time. Cooling systems have to be re-installed, the reactor fuelled and so on. It could be six months to a year before the reactor is up and running. This will open up a new source of plutonium for North Korea's nuclear weapons programme.

Pyongyang's references to its highly-enriched uranium activities are puzzling experts and are less clear. This provides an alternative basis for a nuclear weapon. But nobody knows how many secret enrichment plants North Korea may have or the level to which they may already be enriching nuclear material.

So in many ways its back to square one in terms of nuclear diplomacy. But six years have passed since 2007 and in the intervening period North Korea's missile capabilities - the means by which it might eventually seek to deliver a nuclear warhead - have improved significantly.

A South Korean foreign ministry spokesman said that if true, the North Korean move would be "highly regrettable".

Chinese foreign ministry spokesman Hong Lei called for restraint from all sides to resolve the "complex and sensitive" situation.

'Adjust and alter'

The reactor at Yongbyon - which was the source for plutonium for North Korea's nuclear weapons programme - was closed in July 2007 as part of a disarmament-for-aid deal.

The cooling tower at the facility was later destroyed, but then the disarmament deal stalled.

Part of the reason the agreement fell apart was because the US did not believe Pyongyang was fully disclosing all of its nuclear facilities - a suspicion later bolstered when North Korea unveiled a uranium enrichment facility at Yongbyon to US scientist Siegfried Hecker in 2010.

While it appeared to be for electricity generation purposes, Mr Hecker said the facility could be readily converted to produce highly-enriched uranium for bombs.

The statement, carried by KCNA news agency, was attributed to a spokesman for the General Department of Atomic Energy.

Yongbyon nuclear complex

  • North Korea's main nuclear facility; thought to have produced the material for 2006 and 2009 nuclear tests
  • Reactor shut down in July 2007 as part of a disarmament-for-aid deal; Cooling tower dismantled in 2008
  • IAEA inspectors banned in April 2009 when North Korea pulled out of disarmament talks
  • Experts believe that, if re-started, reactor could make one bomb's worth of plutonium per year
  • A uranium enrichment facility was revealed in 2010. An American nuclear scientist said centrifuges appeared to be primarily for civilian nuclear power, but could be converted to produce highly enriched uranium bomb fuel
  • Nuclear test based on uranium device would be harder to monitor than plutonium

The department had decided "to adjust and alter the uses of the existing nuclear facilities" including "readjusting and restarting all the nuclear facilities in Nyongbyon [Yongbyon] including uranium enrichment plant and 5MW graphite moderated reactor".

The work would be put into practice without delay, the statement said. It also attributed the move to the need to generate more electricity.

In a November 2010 report following his visit to Yongbyon, Siegfried Hecker said based on what he saw he believed North Korea could "resume all plutonium operations within approximately six months" at Yongbyon if so inclined.

The reactor can produce spent fuel rods that can be made into plutonium - which experts believe North Korea used for its nuclear tests in 2006 and 2009. It is not clear whether plutonium or uranium was used in the February test.

The reference to altering nuclear facilities could suggest that North Korea may begin openly enriching uranium to weapons-grade levels, which would give it a second, faster route to making nuclear weapons, reports the BBC's Lucy Williamson, who is in Seoul.

Timeline: Korean tensions

  • 12 Dec: North Korea fires three-stage rocket, in move condemned by UN as banned test of long-range missile technology
  • 12 Feb: North Korea conducts an underground nuclear test, its third after tests in 2006 and 2009
  • 11 Mar: US-South Korea annual joint military drills begin
  • 19 Mar: US flies B-52 nuclear-capable bombers over Korean peninsula, following several North Korean threats
  • 27 Mar: North Korea cuts military hotline with South
  • 28 Mar: US flies B-2 stealth bombers over Korean peninsula
  • 30 Mar: North Korea says it is entering a "state of war" with South Korea
  • 2 Apr: North Korea says it is restarting mothballed Yongbyon reactor

In the weeks since the nuclear test, North Korea's rhetoric has escalated - including multiple threats of attacks on US bases in South Korea and Japan, and on South Korean border islands.

But the US, which has in recent days flown B-52 bombers, B-2 stealth planes and F-22 stealth bombers over South Korea in a show of strength, says it is seeing no signs of increased military activity in North Korea.

"Despite the harsh rhetoric we're hearing from Pyongyang, we are not seeing changes to the North Korean military posture, such as large-scale mobilisations and positioning of forces," White House spokesman Jay Carney said.

But he said the US was "monitoring the Korean situation very diligently".

Defence officials told reporters that a US Aegis-class warship capable of defending against missile strikes had also been moved to the south-west coast off South Korea.

This would offer "greater missile defence options should [they] become necessary", an official told Reuters news agency.

Reports also suggest the US is moving a sea-based radar platform called SBX-1 into the western Pacific so that it can monitor North Korea.

    All this talk about missile range, its nonsense, you would just have to ship one over secretly and then detonate it, if drugs can get through why not a missile?

    The thing is, there are only a couple of places in the world who would do such a thing and a US response with its big arsenal would mean total country annihilation, the whole population.

    So everyone put down their weapons and get on..

    "Yes, North Korea are not democratic, but it is perfectly possible to argue that we are not either - afterall we have had the same non-elected head of state for 60 years now."

    Yes, only the other day my neighbour had all of his close friends and family executed because he dared to criticise the queen.

    America now moving into 80 plus countries that it has attacked since WW2 if anyone still has any questions about who is the aggressor, has the highest kill rate (multiple times more than nazi germany) then you believe that N Korea has state media and we don't. BBC anyone?

    I feel a bit sorry for North Koreans. They've spent years as an ostracised, and I think a friendly international hand would help no end. Send someone in to talk, or invite them to us.

    Perhaps PC Kelly Jones would go, she likes a nice trip.

    Isn't this reactor the same type as Chernobyl?
    Has the reactor core gone through a "cooling down" cycle? If it was mothballed in 2007 and a cooling tower removed, then it is probably useless! I would fear a "nuclear problem" caused by "cock up" rather than conspiracy,

    All the talk coming from North Korea cannot detract from the simple truth - North Korea is poor. It does not and cannot produce enough to support its population. It is a poor nation led by a small group of people who cannot see past their own determination to pretend to be wealthier, more powerful and more successful than they really are. I feel sorry for the majority of their population.

    Smart monitoring of North Korean manoeuvres will pay rich dividends. The North Korean leader is playing poker. Little does he realize that his game could go horribly wrong! His every move is being monitored. The Americans are ready for a show-down but will not act unwisely. China needs to do more and be more pro-active. Obviously Kim Jong-un has not thought through his actions carefully. IMMATURE

    Live and let live. Global dictator ship of standards is wrong.

    In 1938, Neville Chamberlain thought like you. Had Britain, French and the Yanks maned up a bit and acted to get rid of Hitler, millions of lives would have been saved. Although I expect those lives would have been lost in war against the Russians....

    They will do and say everything and anything APART from actually going to war. "

    They may not get a choice in the matter. Someone in Washington may think it better to deal with them now, while they only have a few small-yield nuclear weapons than to have to deal with them later when they have become a true global threat.

    If as experts say is true, that North Korea does not have the missile capability of reaching the US Cities, then this is simply Kim Jong-un trying to flex his muscles.
    However, if there is any evidence of technology being developed to threaten the USA then Washington will hit military targets hard.

    It looks like Kim Jong-un is seeing how far he can push the USA without repercussion

    "All power is given, not taken. The people of NK may be saps now but who gave power to those in charge? They did. It wasn't taken from them by force"

    I'll think you will find it was in that the people of NK have no choice in a one party state. Should they decide to protest about it they will find themselves on the wrong end of tanks and facing a lengthy period of "re-education".

    The USA have no interest in keeping that area peacefull. Things were progressing very well under the Clinton administration and then Bush came along and basically tore up all the agreements. Without conflict the USA would have no excuse for having the military presence in that region.

    When did you last hear of North Korea attacking anyone?
